According to NOAA scientists using the Ocean Land Color Imager (OLCI), a significant harmful algal bloom has developed off Florida’s central west coast panhandle.
Currently situated offshore, this “blob” is not yet affecting coastal residents or visitors directly. However, as it drifts closer to shore, more pronounced human impacts are expected.
Meanwhile, marine life is already being harmed by the red tide caused by Karenia brevis algae.
NOAA warns that these toxins can lead to devastating consequences for fish populations, causing respiratory issues and mortality among sea turtles, manatees, birds, dolphins, and other marine animals.
Recent hurricanes Helene and Milton have stirred up a massive bloom of toxic algae off Florida’s coast, sparking concerns among scientists at NOAA about potential health hazards and environmental impacts in the coming days and weeks.
The “blob” is actually a widespread outbreak of Karenia brevis, also known as red tide, which can cause respiratory problems and eye irritation in humans, while posing a deadly threat to marine life and leading to shellfish closures.
As these blooms are often patchy, their effects vary by beach and throughout the day, making it crucial for residents and visitors alike to stay informed about conditions at specific locations.
The longevity of a harmful algal bloom (HAB) off nearshore Florida waters is influenced by various physical and biological factors, including sunlight, nutrient availability, salinity levels, wind direction, and water currents.
Researchers are closely monitoring these conditions to predict the duration and trajectory of this particular bloom using forecasting tools similar to those used for seasonal weather predictions.
The National Centers for Coastal Ocean Science (NCCOS) tracks HABs daily and issues regular forecasts for red tide blooms in the Gulf of Mexico and East Coast of Florida, providing critical information for managing these events effectively.
